Rumors have been running rampant that Anthrax will tour this year with former vocalist Joey Belladonna. This rumor began supposedly when Shadows Fall drummer Jason Bittner said that Anthrax drummer Charlie Benante more or less copped to it in a conversation.

The only confirmation we have at this time is that the official Dynamo Open Air Festival website (Netherlands) has posted this:

"The line-up for Dynamo Open Air 2005 is slowly coming together.
Six bands are now confirmed. With great pride we can announce that
ANTHRAX
are celebrating their 25th anniversary at Dynamo with a very special performance.
For the occasion they will bring Joe Belladonna, Anthrax frontman until 1993.
Under the monicker "The Greater Of Two Evils,"
Anthrax will perform at Dynamo with two singers!
Earlier we already announced."

Another rumor circulating is that Sharon Osbourne has promised Anthrax a slot on Ozzfest 2005, contingient on the inclusion of former vocalist Joey Belladonna on the tour.
